Описание (английский):

Provides a series of graphical symbols to represent tectonic phenomena. This part includes symbols for: strata, faults, joints and schistosity; folds and monoclines; lineations and axes. Table 1 gives the basic symbols; table 2 shows special planes; table 3 contains slopes; table 4 represents folds and monoclines. Fourteen figures illustrate the descriptions.

Overview

ISO 710-7:1984 - "Graphical symbols for use on detailed maps, plans and geological cross-sections - Part 7: Tectonic symbols" is an International Organization for Standardization (ISO) document that defines a standardized set of graphical symbols specifically for representing tectonic phenomena on large‑scale geological maps, plans and cross‑sections. Published as part of the ISO 710 series (developed by ISO/TC 82, Mining), this part focuses on strata, faults, joints and schistosity; folds and monoclines; and lineations and axes. The standard includes four symbol tables and fourteen illustrative figures to guide consistent depiction.

Key topics and requirements

Principle of representation: Symbols describe the observed (existing) state, not genetic interpretations.

Planes and lineations:

Planes are shown by their traces on the reference plane (single or thicker lines depending on type).
Lineations are represented by projections (compound line of alternate dots and dashes) with added modifiers to indicate origin and orientation.

Certainty levels: Symbols can be varied to indicate certain, probable or possible existence/orientation of features.

Fault types and modifiers:

Basic and additional symbols for normal faults, reverse faults/overthrusts, strike‑slip faults, and mixed types (combinations of symbols).
Use of short lines, triangles, or right‑angled ticks to show dip direction, hanging‑wall/footwall relationships and movement sense (sinistral/dextral).

Slopes and inverted strata: On plans, slope is shown with arrows; inverted strata use curved arrows to indicate overturned orientation; dip angle may be annotated in degrees or grades.

Folds and monoclines: Symbols for crest/trough lines, axial planes and fold axes; additional inked symbols (diamonds, triangles) indicate anticlines/synclines and their certainty.

Tables & figures: Table 1 (basic symbols), Table 2 (special planes), Table 3 (slopes), Table 4 (folds/monoclines), plus 14 illustrative figures.

Practical applications and users

ISO 710-7 provides a unified visual language for geological mapping and technical documentation. Typical users and applications include:

Field geologists and structural geologists preparing maps and cross‑sections.

Mine planners and mining engineers producing mine plans where fault geometry and lineations affect design and safety.

Civil and geotechnical engineers documenting ground conditions for infrastructure projects.

Cartographers and GIS specialists implementing standardized symbol sets in map products and digital layers.

Academic researchers and consultants ensuring consistent representation in reports and publications.

Using ISO 710-7 improves clarity, reduces misinterpretation of structural data, and supports interoperability between maps, technical drawings and GIS databases.
